COVID-19 is diagnosed with a viral test. This may also be called a PCR test or antigen test. It looks for evidence of the virus in your breathing passages or lungs (respiratory system).
The test is most often done on a sample from the nose, throat, or lungs. It's sometimes done on a sample of saliva. One way a sample is collected is by putting a long swab into the back of your nose.
If you have questions about COVID-19 testing, ask your doctor or go to cdc.gov to use the COVID-19 Viral Testing Tool.
